PVC HF Welding Film Hot Air Ultrasonic Welder For Plastic Film

Characteristics:                                                                                                                          

1. High frequency tarpaulin welding machine can be chosen and choose according to user needs.
2. Length, width and radian of welding area can be adjusted by welding die.
3.There is 750mm free space behind the electrode which makes the machine suitable for big scale manufacturing that require extensive material handling. The dimension of product handle platform can be made as client request.

4. For getting better welding effect, install laser scanning system inside the machine to get precise welding position.
5. European model squareness high frequency vibration bos, more reliable and stable in output

Radio Frequency
This type of welding only works with thermoplastics that have a high dielectric constant. In this process, an electric field is generated near the joint, the direction of which is alternated approximately twenty-seven million times a second. Every time the electric field changes, the dipole molecules of the polymer attempt to flip around to realign themselves to the new field orientation. Because this movement is impaired by inertia and friction, the molecules do not flip in unison. This constant relative movement of the molecules results in intermolecular friction which results in heat and, subsequently, melting. Radio Frequency welding typically has weld cycle times from two to five seconds and can handle parts from approximately one-thousandths inches thick to fifty-thousandths inches thick.
